AR-15

Semiautomatic version of the M-16 used by the United States military, legal for civilian ownership in most states thereof. Uses the .223/5.56 NATO round. Like the M-16, it's accurate but not very reliable because of its direct gas impingement system.

My buddy got killed by home invaders because his AR-15 jammed. He should have bought an AK or FAL.

AR 15

A scary black aussault rifle that shoots fully-semi automatically and is easy to obtain. A weapon of choice for shcool shooters, white supremest, and alt-righters

AR 15’s are responsible for 100,000 deaths each year

AR-15

An overrated plinker owned by far too many people, mostly trendy try-hards, that must be broken down and cleaned more often than the AK to keep it running reliably and is more complicated and tedious to break down and clean than the AK to boot. In return for this trouble you'll get an extra MOA of accuracy that you'll never need in a real world combat or personal defense situation

The AR-15 is a fun toy but when they SHTF, I am reaching for my AK-74.

AR-15

The AR-15, short for Assault Rifle, is a lightweight, magazine fed, .223 caliber, automatic rifle. Can tear anybody to pieces in seconds. A favorite or Pastor Troy.

Pastor Troy: The police pull us over. They friskin niggas, they tearin' ma truck up. But they ain't find shit..... but my AR-15. When I saw the cracka pull out the gun... I went and open the police car door and got in ma muthafuckin' self.

AR-15

The (somehow completely legal) firearm of choice for mass shootings in the US, this firearm not only can fire many different sizes of ammunition, but ultimately results in the thoughts and prayers of members of the US government.

“There was yet another mass-shooting that involved and AR-15. Now we get to listen to NRA activists condescendingly shit on everyone about how the “AR” stands for “ArmaLite”, not “Assault Rifle”, instead of talking about the actual problem.
